CHAI hits $68M ARR with 3X annual growth and $1.4B valuation, unveils AI safety framework

CHAI, a customised chatbot platform, has reached $68 million in annual recurring revenue and achieved a $1.4 billion valuation whilst maintaining a 3X annual growth rate over three years. The Palo Alto-based company has implemented comprehensive AI safety measures aligned with the EU AI Act and NIST AI Risk Management Framework. CHAI employs a real-time classifier to detect suicidal ideation and self-harm content in conversations, enabling immediate intervention before unsafe behaviour progresses. The platform logs user conversations on secure servers with anonymised auditing using HIPAA-like privacy protocols. When users express distress, the AI directs them towards helplines, mental health professionals or trusted contacts rather than providing medical advice. CHAI has published its methodology in an official safety framework paper.
